HAY RAKE AND STACKER.

SPECIFICATION forming part of Letters Patent No. 14,795, dated December2, 1902. l Application filed February 8, 1902. Serial No. 93,168. (Nomodel.)

To all whom it may concern: Be it known that 1, ANDREW H. GRAVES,citizen of the United States, residing at Lamoni, in the county ofDecaturand State of Iowa, have invented certain new and usefulImprovements in Hay Rakes and Stackers;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention has relation to machines specially designed for stackinghay, grain,

and the like, the purpose being to improve the general structure and toprovide an implement for the purpose aforesaid which will be simpleinconstruction, efiective in operation, and easy of manipulation.

In its organization the machine comprises a rake or load-lifter,carrying-arms therefor comprising sliding members, manually-operatedmeans for tilting the said arms to raise invention.

finally embodied in the subjoined claims.

In the drawings hereto attached and forming a part of the specification,Figure 1 is a perspective view of a machine embodying the Fig. 2 is aside elevation thereof, the rake being shown lowered by full lines andlifted by dotted lines.- Fig. 3 is a perspective view of the means fortilting the arms of the raketo efiect a raising and lowering thereof, asshown by the full and dotted lines in Fig. 2. Fig. at is a longitudinalsection showing the rake elevated as it will appear when discharging theload upon the stack. Fig. 5 is a transverse section about on the line:12 a; of Fig. 2 looking in the direction of the arrow. Fig. 6 is adetail perspec tive view of the guide-rollers for the rakearms and thecontiguous parts.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The frame may be of any construction and, as shown, compriseslongitudinal beams 1 and a connecting cross-bar 2 and is supported uponground-wheels 3 and caster-wheels 4, the latter being applied to thecross-bar 2. The ground-wheels 3 are applied to the ends of the axle 5,which is mounted near its ends in the beams 1 near their frontextremities. Posts 6 rise vertically from the rear corners of the frameand are joined attheir upper ends by a cross-bar 7 Guides 8 connect theupper ends of the post 6 with the longitudinal beams 1 and have theirend portions curved. The guides 8 strengthen and brace the parts 1 and 6and also act to lengthen the arms carrying the rake or load-lifter 9.The axle 5 at the end of the machine forms a tie for and braces-thebeams 1 and, in conjunction with the cross-bar 2, formsa tie for thelongitudinal members of the frame.

The rake or load-lifter 9 is firmly attached to the arms A, composed ofsliding parts or braces 10 and 11, mounted to tilt upon the axle 5, soas to effect a raising and lowering of the rake, as shown by the fulland dotted lines in Fig. 2. The sections 10- are connected near theirrear ends by a cross-barlZ and at or near their front ends by across-bar 13, the end portions of which are bent, as shown at 14, toembrace the sections 10 and 11, as shown most clearly in Fig. 5. Thesections 11 have wings 15 at their inner or rear ends to embrace theupper and lower edges of the sections 10, so as to support thesaid-sections 11 and give proper direction thereto inthelengthening andshortening of the arms due to the sliding movements of the parts 11. Theforward ends of the sections 11 are curved downward and the rake-head isrigidly attached thereby enabling the rake to havea maximum it range ofmovement when being elevated to deliver the load upon the stack andlowered to the position shown by the dotted lines in Fig. 2. The pulleys17 and 18 are loosely mounted upon journals of a bracket 19, fitted toeach end of the cross-bar 16.

The arms A are supported near their front ends by the axle 5, and theirrear ends are connected by links 20 with the beams 1 a shortdistancefrom their rear ends. A rockshaft 21 is journaled to the cross-bar 2 andis provided with an operating-lever 22, having a hand-latch 23 forcooperation with a notched segment 24, attached to the cross-bar 2 forholding the rock-shaft in an adjusted position. The ends of therock-shaft are bent, as shown at 25, and are pivotally connected tolinks 26, having pivotal attachment to the rear ends of the pivoted armsA. The links 26 have inner extensions 27, forming stops to engage withthe bent ends or arms 25 of the rock-shaft and hold the parts 25 and 26in alinement, as shown most clearly in Fig. 3 and by the dotted lines inFig. 2. In one position of the lever 22 the arms A are lowered at theirrear ends and raised at their front ends, as shown bythe dotted lines inFig. 2, and in the other extreme position of the said lever the arms Aoccupy an approximately horizontal position and the rake is lowered, soas to rest upon theground forconvenience of receiving the load, as shownby the full lines in Fig. 2.

The machine is moved from place to place by running upon ground-wheels 3and casterwheels 4, the draft being applied thereto in any convenientWay. When positioned for use and it being required to load the rake, thelever 22 is operated to lower the rake into the position shown by fulllines in Fig. 2, and after the load is received thereon the lever 22 isagain operated to raise the rake to the position shown by dotted linesin Fig. 2, the inner ends of the arms A being in a position to besupported by the ground and the connections 25, 26, and 20 oppositelyinclining and mutually bracing each other, asindicated by the dottedlines in Fig. 2. After the rake has been loaded it is elevated todeposit the hay or grain upon the stack by means of cords or ropes 28,which pass over guide-pulleys 29 at the upper end of the vertical frame,comprising the post 6 and cross-bar 7, thence around otherdirection-pulleys 30 at the lower end of said vertical frame to behitched to the operating power in any preferred man ner. Inasmuch as itis common to hitch the ends of the cords 28 to a draft-animal or teamand in order to compensate for any difference in movement of theanimals, it is preferredthat the cords or ropes 28 constitute parts of asingle line which passes around guide-pulleys 31 near the outer or frontends of the pivoted arms A. It will thus be seen that the cord or ropeis free to adapt itself to any difference in movement of the endsthereof by reason of the system of direction-pulleys shown anddescribed. When the cords or ropes 28 are drawn together, the rake 9 iselevated and the pulleys 17 and 18 travel upon guides 8 andsimultaneously with the elevation of the rake the arms are graduallyextended until when the rake is approximately in a perpendicularposition the arms are extended to their utmost limit. Upon slacking thecords or ropes 28 the rake will automatically assume a normal positionby gravitative force, resulting from superior weight in the rear of therake when elevated, the parts being so disposed as to prevent movementof the rake past a vertical plane extending through the center ofgravity.

Having thus described the invention, what is claimed as new is- 1. Incombination a rake or load-lifter, an extensible support therefor, meansfor raising and'lowering the rake, and a guide for directing the rake inits movements and simultaneously extending or contracting the supporttherefor, substantially as specified.

2. In combination, a rake or load-lifter, an extensible supporttherefor, means for raising and lowering the rake, and an inclined guidehaving its end portions curved for directing the rake in its movementsand simultaneously eflecting a lengthening or a shortening of theaforementioned support, substantially as set forth.

3. In combination, an approximately horizontal frame, a substantiallyvertical frame, a guide between the two frames likewise serving to bracethe same, a pivotal support provided with a rake or load-lifter anddirected in its pivotal movements by the said guide, and actuating meanstherefor, substantially as set forth.

4:. In combination,framesdisposedapproximately at a right. angle to eachother, guides bracing the frames,a pivotal support provided with a rakeor load-lifter and comprising extensible sections, engaging meansbetween the movable sections and the said guides, and actuating meansfor operating the pivotal support, the parts being combined to efiect asimultaneous elevation of the rake and extension of its pivotal support,substantially as set forth.

5. In combination, a pivotal support comprising extensible sections, arake or loadlifter applied to the outermost section, means foradjustably supporting the inner or rear end of the pivotal support, aguide, cooperating means between the guide and outermost section of thepivotal support, and operating means for elevating the rake to dump theload, the sections of the pivotalsupportbeingsimultaneously extended,substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
